The Zero 1 system supplied the track with a 18 V sinusoidal alternating current at the local mains frequency with a 32-bit control word replacing every third cycle. The decoder module in the locomotive would switch either the positive or the negative half-cycle of the square wave to the motor according to the desired direction of travel.
GEOS (Graphic Environment Operating System) is a discontinued operating system from Berkeley Softworks (later GeoWorks).Originally designed for the Commodore 64 with its version being released in 1986, enhanced versions of GEOS later became available in 1987 for the Commodore 128 and in 1988 for the Apple II.
The 37.5 mm length is not derived by a certain scale ratio. While HO scale is a 1:87 scale (3.5 mm to 1 foot), resulting in a 16.5 mm (0.65 in) gauge from real life prototype 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard gauge standard gauge. Conversely, modeling standard gauge in Lego trains would yield a scaling of (37.5:1435 =) 1:38.3.
Digital Command Control (DCC) is a standard for a system for the digital operation of model railways that permits locomotives on the same electrical section of track to be independently controlled. The DCC protocol is defined by the Digital Command Control Working group of the US National Model Railroad Association (NMRA).
Märklin Digital was among the earlier digital model railway control systems. It was a comprehensive system including locomotive decoders (based on a Motorola chip), central control (Märklin 6020/6021), a computer interface (Märklin 6050), turnout decoders (Märklin 6083), digital relays (Märklin 6084) and feedback modules (Märklin s88/6088).

A scratch-built Russell snow plow is ...
In 1990, GeoWorks (formerly Berkeley Softworks) released PC/GEOS for IBM PC compatible systems. [4] Commonly referred to as GeoWorks Ensemble, it was incompatible with the earlier 8-bit versions of GEOS for Commodore and Apple II computers, but provided numerous enhancements, including scalable fonts and multitasking on IBM PC XT- and AT-class PC clones.
Timesaver is a well-known [1] model railroad switching puzzle (U.K. English: shunting puzzle) created by John Allen. [2] It consists of a specific track layout, a set of initial conditions, a defined goal, and rules which must be obeyed while performing the shunting operations.
